Returning to the time before the college entrance examination, Wu Tong made up her mind to study hard and change the tragedy of her previous life, becoming her parents' pride.
From being ...
Chapter 430 God Comes
Compared with the huge Jinwu project, Wu Tong had to focus on the progress and difficulties to overcome. They were just doing magnetohydrodynamic power generation, which was quite familiar and had a certain basic breakthrough, so it was easy enough.
After seeing Yi Lao off, Wu Tong took three days to work with Lu Xiao to complete the mathematical model she had established, and successfully embedded it into the research and development of the motion laws of the plasma stellarator device designed and developed by Lu Xiao, waiting for his final breakthrough to turn this huge design idea into a real control solution.
"For the next part, I'll have to trouble Brother Lu. If you need assistance with programming talent, please tell me and I'll ask for a loan from above!" Wu Tong spread her hands. As the general manager, this was her unshirkable responsibility of selecting people.
"I have some basic knowledge of programming, so I don't need to ask for help from outsiders!" It has been basically completed, and Lu Xiao couldn't help but breathe a sigh of relief. Finally, he has caught up with Wu Tong's progress. Although he is a pioneer, Lu Xiao doesn't want to be beaten to death on the beach. Keeping up with Wu Tong's progress is his basic requirement for himself.
In other words, he should be thankful that the field of physics was relatively easy for him at that time. With extra energy, he did not waste his good talent and mathematical skills, and dabbled in research on programs, artificial intelligence, etc.!
At this moment, it just happens to be useful, or it has always been of good use. For example, the previous simulation test system was developed under his leadership...
Wu Tong certainly did not stop and rest after entrusting the design of the constraint control scheme to Lu Xiao. After doing this, she immediately opened the experimental data she brought back from the southwest and found the lithium sheet scanning test data she brought with her after the experiment and began to carefully review and deduce it.
She brought over a batch of lithium sheets, which were placed at different positions on the first wall. However, there were very few samples that had actually been bombarded by the neutron beam. Fortunately, they found such samples in that experiment and did not need to repeat the experiment.
The cost of an experiment is a bottomless pit, and there is not enough equipment in the country to allow her to try experiments endlessly! Thank you for your lucky care!
The lithium sheet that had undergone the fusion reaction was like a dying piece. The strong neutron radiation destroyed most of the metal bonds and became a derivative that was almost fragile. Lithium itself is not a strong and durable metal material.
However, this batch of specially prepared lithium sheets also completed their mission. Wu Tong used them to test the rate at which lithium recovered neutrons. She observed traces of the recovery of reactants on them.
This trace also proves that Wu Tong's sandwich filling design idea is indeed feasible.
Although, this design idea still has many problems to be solved, such as how much liquid lithium is needed in the liquid lithium recovery layer to achieve a delicate balance in processing?
For example, if the energy carried by neutrons is too high, how can the liquid lithium layer be safely recovered and the absorbed elements released? How can the neutron beam be safely equipped with the collection of the liquid lithium layer, obediently cooperate, instead of running wild in this process and causing damaging impacts on the entire recovery system...
The thickness of the liquid lithium layer is the most fundamental and important difficulty to derive. If it is too thick, it will not work; if it is too thin, it will be useless. Neither too thick nor too thin is good.
The more liquid lithium layers, the better. At this time, we cannot talk about quantity and strength. If it is too thick, a large amount of tritium will be retained inside the liquid lithium, which will drag down the recovery efficiency. The thickness of the liquid lithium layer is also proportional to the difficulty of the project. Every increase will greatly increase the difficulty of preparation...
If one thing goes wrong, it may affect the safety of the entire reactor, making it the weak link in the barrel principle of the entire reactor and causing a safety accident!
Of course, it is not good to be too thin. A too thin liquid lithium layer will directly affect the proliferation rate of tritium.
Just like applying fertilizer, if the fertilizer is not strong enough, the crops will not grow. If the liquid lithium layer is too thin, there will naturally be no work efficiency. After all, the half-life of a free neutron is only about 10.6 minutes, which means that while they have to consider the transmutation of neutrons with other elements, they also have to consider the decay of neutrons themselves.
The most ideal situation would be to use liquid lithium to recover neutrons before they are reflected again at the metal interface. However, it is not easy to do this!
This appropriate amount requires Wu Tong to combine the scanning data and the efficiency data of lithium-neutron energy recovery to build a model and deduce it step by step.
Details determine success or failure. Just having a design idea does not mean that everything will be fine. It can only be said that the design idea is only the first step before departure. There is still a long way to go, and each of the above issues must be taken into consideration.
Although she has the general direction, she still needs to continue to enrich, refine and perfect the details.
This is also the core design idea and solution of the entire project, and one of the most core issues that must be overcome, so that their entire first wall can be considered stable and complete.
The material of the first wall is mainly radiation-resistant, allowing an out-of-control neutron beam to pass through. The HC-1 material of the first wall is used to penetrate and slow down the unbalanced neutron beam. The heat-resistant coating reinforcement coating further enhances the resistance to high temperatures. The subsequent liquid lithium recovery system absorbs neutrons and releases tritium, and uses the special metal reflective layer on the outermost layer outside the liquid lithium layer to bounce back the incompletely reacted neutrons.
At this time, Wu Tong had an idea and applied an upward force to the recycling system, pulling the recyclables upward into the fuel chamber and re-entering the fusion cycle.
The principle behind this is that at the working temperature of liquid lithium, both tritium and helium exist in gaseous form, and they are immiscible with liquid lithium.
At this time, the recovered tritium exists in the form of gas, giving it an upward force, allowing it to be recovered at the top of the device and re-injected into the reaction chamber to participate in the reaction, achieving a benign cycle of utilization. Similarly, it solves the shackles that hinder the formation of controlled nuclear fusion in the world.
Thanks to the predecessors' persistent R&D experience, which laid a solid foundation, Wu Tong combined these previously fragmentary experience data and deduced them into the sandwich snack design concept that now amazes the entire project.
…
The detailed direction, under Wu Tong's continuous deduction, tends to be perfect. Wu Tong conducted a running simulation in the deduction space. The tritium trapped in the liquid lithium was successfully separated under the solution derived by Wu Tong, and entered the cycle, becoming a good substrate for the next fusion reaction.
